AP PSYCHOLOGY

Detailed explanation-1: -One of them is called magnetic resonance imaging (MRI), which looks at the structure of the brain and another is functional magnetic resonance imaging (fMRI), which looks at the brain’s function. fMRI measures brain activity by tracking changes in blood flow to the brain.

Detailed explanation-2: -An fMRI scan is a special type of MRI that shows how different parts of your brain are working. They help doctors measure blood flow in the brain without having to do surgery. fMRI imaging is a safe, non-invasive way to diagnose conditions and to find out if certain treatments are working.

Detailed explanation-3: -While an MRI scan allows doctors to examine a patient’s organs, tissue, or bones, “an fMRI looks at the function of the brain, ” Dr. Zucconi explains.

Detailed explanation-4: -Functional magnetic resonance imaging, or FMRI, works by detecting the changes in blood oxygenation and flow that occur in response to neural activity – when a brain area is more active it consumes more oxygen and to meet this increased demand blood flow increases to the active area.

Detailed explanation-5: -New research is emphasising the integration of fMRI with other techniques, particularly electrophysiological. In conjunction with MRI methods for characterising pathological load, fMRI promises a refined understanding of when disease processes begin and how they can be modified by new treatments.
